DCA-180SSK — GENERAL INFORMATION (OPTIONS)

CAUTION :

The DCA-180SSKis powered by a 4 cycle, water cooled, turbocharged KOMATSU Model SA6D108E-2 diesel gasoline engine. This engine is designed to meet every performance requirement for the generator. Reference Table 7, page 25 for engine specifications.

In keeping with MQ Power's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.

The basic controls and indicators for the DCA-180SSK generator are addressed on the following pages.

Mechanical Governor System

The mechanical governor system control the RPM of the engine. When the engine demands increase or decrease, the mechanical governor system regulates the frequency variation to ±1.0%. The electronic governor option increases frequency variation to ±0.25%.

Electronic Governor System

The electronic governor system is made up of two parts, an electronic controller that monitors frequency variation as the load increases and decreases and an electronic actuator that controls the engine throttle. The frequency is regulated at ±0.25 to help protect sensitive equipment.

JacketWater Heater (OPTIONAL)

The jacket water heater is a 1500-watt heater designed to keep the coolant from freezing in the engine block. The heater is thermostatically controlled and once an acceptable engine temperature is achieved it will cycle on and off, operating only about 1/3 of the time. This becomes a very energy efficient option compared to a direct immersion block heater. It is designed to keep the engine between 100 and 120 degrees Fahrenheit. This is not a throwaway heater. It is completely serviceable.

In normal conditions, 20 to 15 minutes is all that is required to raise the engine temperature of a cold engine to 100 degrees Fahrenheit.

ALWAYS unplug the jacket water heater before servicing.

There is a bleed screw on the valve on the engine block. After service of either the heater or the cooling system, it is possible to create an air bubble in this area. The air bubble would prevent hot water created by the jacket water heater from circulating, if the air bubble were not allowed to escape. This bleed screw allows for the bleeding process to be accomplished.

Battery Charger (OPTIONAL)

The battery charger will operate in a ‘BOOST’ mode until the battery’s current acceptance falls to 70% of the charger’s rating. The charger will then go into a ‘FLOAT’ mode, where it discharges a lower voltage until an AC failure, or the battery is discharged.

FuelWater Separator

The fuel water separator separates water mixed in the fuel. It has an indicator to let the operator know to drain the water. See maintenance section for instructions how to drain water from separator.
